Abstract

The invention relates to a benzocyclobutene polysiloxane polymer monomer or resin and a preparation method thereof. The invention discloses a dimethyl-4-benzocyclobutene silicon-based ethylmethyl cyclotetrasome disclosed as Formula (III) and a preparation method thereof. The preparation method of the polysiloxane polymer monomer comprises the following steps:Sequentially adding a tetramethyl-tetravinyl-cyclosiloxane solution diluted by solvent methylbenzene and 4-(1-H-1,1-methyl)silicon benzocyclobutene into a reactor, adding a platinum catalyst after applying a nitrogen atmosphere, and reacting at 60-90 DEG C for 20-40 hours; and adding triphenylphosphine, heating under reflux for 3 hours, cooling, filtering, concentrating the filtrate by distillation, adding methanol, mixing, precipitating, filtering, repeatedly precipitating the solid with methanol, and drying the solid to obtain the polysiloxane polymer monomer product. The product has excellent thermal properties, mechanical properties, electric properties and film-forming properties, and has wide development and application prospects as a high-performance dielectric film material or packaging material in the fields of micro-electronics, aerospace, national defence and the like. (III).

Description

technical field The invention belongs to organosilicon monomer or resin and a preparation method thereof, and relates to a benzocyclobutene polysiloxane polymer monomer or resin and a preparation method thereof. The prepared polysiloxane-type benzocyclobutene resin has excellent properties, and is suitable for high-performance dielectric film materials or packaging materials in the fields of microelectronics industry, aerospace and national defense. Background technique Benzocyclobutene (BCB) materials have been widely used abroad due to their excellent high and low temperature resistance, weather resistance, good air tightness, radiation resistance, especially excellent film-forming properties and moisture resistance. To the military and civilian fields. Common silicone polymers have excellent properties such as high and low temperature resistance, weather resistance, electrical insulation, radiation resistance, flame retardancy, good air tightness, and corrosion resistanc...
